The present invention possesses the advantages of high production efficiency, good cutting quality, simple structure etc.
Description
The present invention relates to a kind of liquid gas high speed precision rod cutter.
Along with the development of industries such as automobile, bearing, machine-building and less, no NEW CUTTING TECHNOLOGY, new technology spread are used; perpendicularity, end face ovality and the weight error of unevenness, end face and the axis of the end face of blanking blank required more and more higher, to guarantee material forming process stabilization, precision height, economical with materials, protection mould and device security.
Blanking commonly used at present has methods such as cutting machine blanking and sawing machine blanking, and mechanically operated cutting machine blanking is low owing to shear rate, no bar clamping device etc., thereby can't obtain satisfied cross section quality and weight error, so many industries can not re-use.The sawing machine blanking can obtain satisfied cross section quality, but it is low to exist productivity ratio, waste of manpower, waste material (stock utilization on average has only about 90%), shortcomings such as cost height.Though the blanking of high speed band saw can be boosted productivity, saw blade cost height, the life-span is low, and waste material (saw kerf place) too, has also increased cost undoubtedly.
The purpose of this invention is to provide a kind of production efficiency height, liquid gas high speed precision rod cutter that shearing quality is good and simple in structure.
Task of the present invention is achieved in that
This liquid gas high speed precision rod cutter, it comprises frame, be located at the shearing die guide rail of upper rack inboard, be located at frame top by cylinder, hydraulic cylinder, piston, the liquid cylinder that piston rod and cylinder body are formed, be located at the slide block of piston-rod lower end, be located at the shearing patrix below the slide block, be located at the shearing counterdie above the die holder, be located at the buffer unit between die holder and the shearing counterdie, wherein it also comprises by clamping mould bases, patrix is fixedly clamped, clamp counterdie, the clamping die guide rail, the material feed clamping mechanism that clamping cylinder and cradle are formed, clamping die is erected at a side of frame, be provided with the patrix that is fixedly clamped on the top that clamps mould bases, be provided with the clamping die guide rail in the inboard that clamps mould bases, clamping cylinder is located at the bottom that clamps mould bases, its piston rod connects with the clamping counterdie, and cradle is located at a side that clamps the mould bases charging.
Because main frame of the present invention adopts the liquid gas drive moving, and is disposable for cylinder charges into compressed air or nitrogen before the work, makes the gas compress energy storage by fluid pressure during backhaul.During cutting stroke, liquid is discharged fast, and gas expansion for doing work promotes slide block and hits downwards, shears bar by the kinetic energy of putting aside in the down stroke, and shear rate reaches 6-7m/s.The module of host module and clamping device all adopts the dichotomic type structure in addition, and bar surface tolerance is not had specific (special) requirements.Therefore compare with background technology, have following advantage:
1, production efficiency height: owing to improved shear rate, thereby improved the shearing number of times and promptly improved productivity ratio;
2, shearing quality is good: owing to adopted the dichotomic type sleeve die, reduced percent defective, improved shearing quality;
3, simple in structure, easy for installation.
The present invention not only can shear bar, changes difform shearing die, also can be used for shearing various section bars, therefore can be widely used in automobile, agricultural machinery, metallurgy and machinery manufacturing industry.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
As shown in Figure 1, the present invention includes main frame and material feed clamping mechanism, main frame comprises frame 5, shearing die guide rail 6, and by the liquid cylinder that cylinder 8, hydraulic cylinder 10, piston 7, piston rod 11 and cylinder body 9 are formed, slide block 4 is sheared patrix 3, shears counterdie 2 and buffer unit 1.Shearing die guide rail 6 is located at the inboard on frame 5 tops, liquid cylinder is located at the top of frame 5, piston 7 is located at the centre of cylinder body 9, make the epicoele of cylinder body 9 form cylinder 8, the cavity of resorption of cylinder body 9 forms hydraulic cylinder 10, and an end of piston rod 11 connects with piston 7, the other end connects with slide block 4, shear patrix 3 be located at slide block 4 below, shear counterdie 2 be located at die holder 19 above, buffer unit 1 is located at die holder 19 and shears between the counterdie 2.Material feed clamping mechanism forms by clamping mould bases 12, the patrix 13 that is fixedly clamped, clamping counterdie 16, clamping die guide rail 17, clamping cylinder 18 and cradle 15, clamp the side that mould bases 12 is located at main frame 5, be provided with the patrix 13 that is fixedly clamped on the top that clamps mould bases 12, be provided with clamping die guide rail 17 in the inboard that clamps mould bases 12, clamping cylinder 18 is located at the bottom that clamps mould bases 12, its piston rod connects with clamping counterdie 16, and cradle 15 is located at a side that clamps mould bases 12 chargings.14 is bar among the figure.
Sequence of movement of the present invention is: the hydraulic cylinder oil-feed of giving the main frame liquid cylinder, the slide block backhaul, clamping cylinder unclamps, and makes the clamping counterdie separate charging with the patrix that is fixedly clamped, clamping cylinder clamps, clamp counterdie and clamp bar, give the hydraulic cylinder oil extraction of main frame liquid cylinder, under the effect of cylinder with the patrix that is fixedly clamped, slide block falls to shearing bar, enters next working cycles then.
